Legs galloping, arms swinging loosely, Philip Rivers sprinted goofily downfield Friday, dug his right foot into the grass, and cut to his left toward the end zone.

Yes.

Philip Rivers ran a post route.

For the first time in training camp, the Chargers devoted on-field time to the Wildcat offense with running back Ronnie Brown taking direct snaps and Rivers lined up at wide receiver.

The Rivers route added some levity to the end of a morning walk-through, but all in all, the package seems to be something the Chargers are taking seriously.

"It's a way to, (against) a team that doesn't handle it well, get some runs," coach Norv Turner said. "I can envision us running it if it matches up with the other team. (Brown) is very good at it. We have other players that handle it real well.

"There are some people who think it takes away from the quarterback, but if it's three to four plays a game, there's some good to be gained from it. Philip's going to get his shots."

The daily grind — the long hours, the meetings, the going against the same teammates — can make life at training camp a bit monotonous.

So, such a small thing as a quarterback going deep can go a long way.

In the afternoon, the route, described by nose tackle Antonio Garay as "Forest Gump-ish," was still a cue for laughter.

Said a wise Brown: "He was ready for the ball. But we don't want to get him hit in any situation where we don't have to."

The first question Rivers was asked at his Friday media conference was about the looseness of the walk-through.

Rivers was sure to emphasize the team was productive, but "anytime you can have fun, enjoy it and still get your work done, that's a positive at this point in camp," Rivers said. "We have great focus, and we'll continue having it to keep improving."

Rivers is 6-foot-5, 228 pounds.

Wide receiver Malcom Floyd said he sees potential.

"Oh, yeah, yeah, yeah," Floyd said with a smile. "He can play receiver; 6-5. I think you can just throw him a fade, and it'll be a touchdown. He can play a little basketball, too, so I wouldn't be surprised if he went up for that ball."
